JavaFX BoxBlur Effect

JavaFX allows us to make the nodes blur by using the JavaFX blur effects. In general, the blur makes the image unclear. JavaFX provides the class javafx.scene.effect.BoxBlur which needs to be instantiated in order to apply the blur effect to the nodes. The Box filter is used in the case of BoxBlur effect in JavaFX.
